The weights and measurements used in commerce were crucial in ancient
agricultural economy. The Bible urges the Jews to be fair in their dealings with
one another (cf. Lev. 19:35-36; Deut. 25:13-16; Pro. 11:1; 16:11; 20:10). The
real problems were not only honesty, but the non-standardized terms and systems
used in Palestine. It seems that there were two sets of weights; a "light" and a
"heavy" of each amount (see The Interpreter's Dictionary of the Bible, vol. 4,
p. 831). Also the decimal system (base of 10) of Egypt had been combined with
the sexagesimal (base of 6) of Mesopotamia.

Many of the "sizes" and "amounts" used were based on human body parts,
animal loads, and farmer's containers, none of which were standardized.
Therefore, the charts are only estimations and are tentative. The easiest way to
show weights and measures is on a relational chart.

A. The three most common weights are the talent, the shekel, and the
gerah.

1. The largest weight in the OT is the talent. From Exod.
38:25-26 we learn that one talent equals 3,000 shekels (i.e., "round weight,"
BDB 503).

2. The term shekel (BDB 1053, "weight") is used so often that
it is assumed, but not stated in the text. There are several values of shekel
mentioned in the OT.

a. "commercial standard" (NASB of Gen. 23:16)

b. "the shekel of the sanctuary" (NASB of Exod. 30:13)

c. "by the king's weight" (NASB of II Sam. 14:26),
also called "royal weight" in the Elephantine papyri.

3. The gerah (BDB 176 II) is valued at 20 per shekel (cf.
Exod. 30:13; Lev. 27:25; Num. 3:47; 18:16; Ezek. 45:12). These ratios vary from
Mesopotamia to Egypt. Israel followed the evaluation most common in Canaan
(Ugarit)

4. The mina (BDB 584) is valued at either 50 or 60 shekels.
This term is found mostly in later OT books (i.e., Ezek. 45:12; Ezra 2:69; Neh.
7:71-72). Ezekiel used the 60 to 1 ratio, while Canaan used the 50 to 1 ratio.

5. The beka (BDB 132, "half a shekel," cf. Gen. 24:22) is used
only twice in the OT (cf. Gen. 24:22; Exod. 38:26) and is valued at one-half a
shekel. Its name means "to divide."
